Functions ¶
func Augment ¶
func Augment(result gostwire.DiscoveryResult, metadata interface{}) (map[string]interface{}, error)
Augment augments the passed metadata with additional plugin-supplied metadata and returns the final result in form of a string-indexed map, ready to be used in JSON marshalling, et cetera.
Types ¶
type Metadata ¶
type Metadata func(gostwire.DiscoveryResult) map[string]interface{}
Metadata is a plugin function that returns (additional) metadata, optionally basing on a discovery result. The returned metadata must be in form of JSON marshallable data (especially struct) and the top-level map string indices, when marshalling into JSON, will become field names inside the metadata toplevel discovery result element.
